AUTOMATIC SIPHONwPUll/IP.

SPECIFICATION forming part of Letters Patent No. 709,662, datedSeptember 23, 1902. Application filed March 5, 1902. Serial No. 96,811.(No model.)

To if/ZZ whom it ina/y concern:

Be it known that I, ALBERT BEUZEK, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvementsin Automatic Siphon-Puur ps;and I do hereby declare the following to be-a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

Thisinvention relates to anim proved siphon apparatus for automaticallydraining a body of water from cellars, cisterns, excavations, and otherplaces, and has for'its object to provide a device of this characterthat is simple in construction and practical and efiicient in operation.

In the accompanying drawings, Figure lis an elevation of a deviceembodying the improved feature. Fig. 2 is a vertical section of theSiphon-cylinder, the connection being shown broken away; and Fig. 3 is ahori- Zontal section on line 3, Fig. 2, looking in the directionindicated by the arrow.

A represents a Siphon-head consisting of an outer casing and an innertubular hub and which will ordinarily be of the cylindrical form shownand of such dimensions as the intended capacity may require. Theapertures 4. through the wall or exterior casing of the Siphon-head openinto the annular space 5, surrounding a central hub B, having apassagerunninglongitudinallytherethrough. The connecting end of a forceor feed pipe 6 is inserted in the lower end of the hub part of the headand opens into the receivingchamber7therein. Anumberofopeningsotin thelower end of the hub part provide waterpassages leading from theannularspace 5 into the receiving-chamber 7. The connecting end of thedischarge-pipe S is inserted in the upper end of the Siphon-head andcomes to a close bearing on the shoulder 10, surrounding the upperdischarge-chamber 1l, which corresponds to the lower chamber 7. Thesetwo chambers are connected by a contracted passage 12, which aids increating the required operative force in practicai working.

The upper or opposite end of the feed-pipe 6 will be connected with awater-supply under pressure and is provided with a controllingvalve 13.The globe 14 incloses a strainer, (not shown,) which may be located atany convenient point between the source of supply and the siphon-head.

In placing the device in position for practical working the Siphon-headis submerged inthe body of water to be drained off, the discharge-pipeleading to the point where the water is to be run off. When thefeed-valve is opened, the water under pressure supplying the operatingor starting force will rush through into the Siphon-head and draw orsuck the water to be drained off through the apertures 4 into theannular space 5, and from there through openings a into the hubreceiving-chamber 7, and then outwardly into the discharge-pipe. Thisoperation will be continuous as long as the Siphon-head is submerged.

The volume of water flowing through the feed-pipe is easily regulated,so that the supply may be greater or less or shut off entirely, ascircumstances may require.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

l. A Siphon-head, comprising an outer perforated casing and an inner hubpart, with an annular space between, said hub part having a continuouspassage longitudinally therel through and chambers located in therespective ends thereof connected by a contracted passage, and thecommunicating openings loetween said annular space and the interior ofthe hub, substantially as set forth.

2. In a draining device, a Siphon-head, comprising an outer perforatedcasing and an inner tubular hub part having a passage longitudinallytherethrough, the passages opening into the lower hub-chamber from saidannular space, the feed-pipe, and the discharge-pipe, connected to theopposite ends of the hub part, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.

ALBERT BRUZEK.
